Kuzmina T. Development of theory and technology for obtaining modified flax fibers of functional purposes

The object is the process of flax fibers modification; the purpose is the reception of modified flax fibers corresponding to functionality by the way of separation of fibers bast bunch by compositional chemical agents in the process of flax straw scattering and emulsification of short flax fibers; the methods are light microscopy, analytical methods of quantitative analysis, ultra-violet spectroscopy, microbiological, computer modeling, methods of mathematical statistics; novelty: new hypothesis of the flax fibers reception under the action of compositional chemical agents in the process of scattering and mechanical processing is theoretically motivated; the mechanism of intensification actions of compositional chemical agents is offered and theoretically motivated; the realizing of preliminary emulsification by compositional chemical agents during modification of short flax fibers is firstly offered; the new methodology of defining geometric parameters of modified flax fibers on the base of the digital representation processing of the fibers is designed; new criteria of estimation of flax fibers structural parameters, as average amount of elementary fibers in the bunch on the transverse fibers microcut and factor of separation are offered; classification of modified flax fibers on functionality is firstly designed; the field of application is the primary conversion of bast raw materials.
